I called a friend to invest in hashflare, he put 2 TH / s through my referral link, but I did not receive my 10%, the 2 TH / s went into his account, the purchase was not confirmed on my reference page, I already sent Email has 6 days, still not obvious.

300 $> 2 TH / s - on the day of purchase
10%> 30%

My friend's purchase came in, but it was not computed on my reference page.
